This invention relatesto an improvement in swings of the type in which aplank or swing board is pivotally supported at spaced invention is tosimplify and strengthen a swing of this character, to enhance itscapacity to afiord healthful and exhilarating recreation and exercisefor children, and to minimize the possibilities of the users of theswing being injured.

Other objects and advantages reside in certain novel features of theconstruction, ar-

rangement and combination of parts which will be hereinafter more fullydescrlbed and particularly pointed out in the appended; j claims,reference being had to the accompany-w .1

ing drawings forming a part of this specification, and in which:

Figure 1 is a view in end elevation showing a swing constructed inaccordance wlth the present invention;

Figure 2 is a view thereof in longitudlnal vertical section taken in theplane of line 2-2 of Figure 1;

Figure 3 is a detail view in vertical section taken on line 33 of Figure1, parts being shown in elevation for the sake of illustration Figure 4is a detail view in horizontal section taken on line 44 of Figure 1,with parts shown in elevation for the sake of simplicity inillustration; and

Figure 5 is a similar view taken on line 55 of Figure 2.

Referring to the drawings it will be seen that the swing embodying thepresent invention includes a pair of spaced supports or end framesdesignated at 1 and 2 and of inverted U-shape. The end frames 1 and 2are of identical construction and, as clearly shown in Figure 1, eachhas spaced vertical legs 3 connected by an integral arch-like upperportion 4. Suspended from each end frame or support is a U-shapedhanger, the hanger suspended from the end frame l-being designated at 5and the hanger being suspended from the end frame 2 being designated at6. The hangers 5 and 6 are of identical construc- ,tion and each'hasspaced side rods or hanger rods 7 connected at their lower ends by anintegral andhorizontally disposed connecting portion 8. The horizontalportion 8 of v each hanger is engaged beneath spaced portions of, aswing board or plank 9. Bearing straps 1O embrace the horizontalportions of the hanger rods below the swing board and are connected tothe swing board by means of fastening devices 11 thereby pivotallyinterconnecting the swing board and the hangfers. The upper ends of thespaced side rods of each hanger are pivotally connected as at 12 toconnecting brackets 13 clamped and otherwise suitably secured to thearched portions of the supports 1 and 2.

The supports 1 and 2 are braced and strengthened by means oflongitudinal connecting rods 14, there being one such con- Jnecting rod14 at each side of the swing.

Each connecting rod 14 is alined with the legs 3 of the end frames 1 and2 with which it is associated and is fastened at its ends to these legsby the fittings 15 shown in detail 15 is of two-part construction, theparts being adapted to form a socket 16 for the end of the connectingrod 14 which the fitting recei'ves. Bolts and nuts 17 secure the partsof each fitting 15 together and to the leg 3 of the frame with which itis associated. Braces 20 are provided betweeneach leg 3 of thesupporting frame and the adjacent portion of the rod 14 connectedthereto, these braces 20 being extended at an angle as shown in Figure 2and being connected to the rod 14 and to the legs 3 by bolts and nuts 21and connecting fittings 22 as shown in detail in Figure 5.

The arched type end frames 1 and 2 are each constructed of a singlepiece of metal and may be tubular. This end frame construction hassubstantial inherent strength and when the end frames are suitablyinterconnected and braced a very rigid and durable construction isprovided. Further than this, the arched portions of the end frames areutilized to directly pivotally support the hangers for the swing boardand as a consequence the swing board and the hangers,
